Changes in v8:
- Add counter_enum.h file
- Simplify COUNTER Kconfig option help text
- Rename generic-counter.c to the more straightforward counter.c
- Update copyright and license boilerplate (use recommended SPDX line)
- Replace EXPORT_SYMBOL lines with respective EXPORT_SYMBOL_GPL lines
- Replace scnprintf lines with sprintf since we're dealing with sysfs files
- Add struct counter_attr_parm to simplify counter_attribute_create parameters
- Rename *_comp_t suffixes to *_unit in order to avoid *_t suffix implications
- List sysfs attribute values verbatim in sysfs documentation files
- Reorganize 104-QUAD-8 driver license boilerplate update to dedicated patch
This revision is functionally identical to the last; changes in this version
were made to improve clarity, formatting and whitespace, and organization. I
also took this opportunity to record some of the new ACKs from the last
submission.
The counter_enum.h file was created to hold the Generic Counter enum helper
functions required by the Generic Counter enum macros (i.e. COUNTER_SIGNAL_ENUM,
COUNTER_COUNT_ENUM, etc.). These helper functions are not intended to be used
directly by driver authors, so I thought it best to keep them separated. Now the
counter.h file contains only macro, functions, and data structures that are
expected to possibly appear in a counter device driver.
The counter_attribute_create function parameter list was large so I reorganized
the parameters into the counter_attr_parm structure, which may be set and passed
by reference to the counter_attribute_create function. Since the show and store
function pointers match with the struct device_attribute show and store function
pointers, I decided to keep them declared as there are here without a typedef --
however, I can typedef them in a future revision if it will improve clarity to
do so.
Heads-up for Jonathan Cameron: you may pick-up the "iio: 104-quad-8: Update
license boilerplate" patch independent of this series; it's the SPDX license
boilerplate update for the 104-QUAD-8 IIO driver.
Sincerely,
William Breathitt Gray
